{title:Description}

{p 4 4 2}{cmd:psgraph} graphs the propensity score histogram by treatment status. 

{p 4 4 2}{cmd:psgraph} can be called without options after {cmd:psmatch2}. In this case {cmd:psgraph} will use
the generate variables {it:_treated} and {it:_pscore}. The options treated and pscore override this
behavior.

{title:Options}

{p 4 8 2}{cmdab:bin}{cmd:(}{it:#}{cmd:)} specifies the number of intervals to use for
accumulating the histogram. The default is {cmd:bin(20)}.

{p 4 8 2}{cmdab:t:reated}{cmd:(}{it:varname}{cmd:)} specifies treatment indicator variable.
Assumes the following: 0 = controls, 1 = treated.

{p 4 8 2}{cmdab:sup:port}{cmd:(}{it:varname}{cmd:)} Common support indicator (0/1).

{p 4 8 2}{cmdab:p:score}{cmd:(}{it:varname}{cmd:)} specifies the propensity score.
